Antitrust law can't force you to develop your products for platforms you don't want to target. You will never see an antitrust decision that Apple must develop a Windows version of XCode, and in fact doing so would probably require a total re-architecture of the iOS platform. You might see antitrust law force Apple to allow sideloading, including apps built by toolchains third parties have hacked together. You're also not required to use a Macbook; the Mini is $500.
